According to a study that emphasizes the importance of a booster dose, early variants of the SARS-CoV-2 virus wane significantly over time and offer essentially no protection against Omicron the same research team discovered that a third COVID-19 mRNA vaccine booster dose produced effective levels of neutralizing antibodies against Omicron in a previous study, which has yet to be peer-reviewed. Pfizer and Moderna mRNA vaccines teach our cells how to make a protein that will trigger an immune response within our bodies.
The new study, published in the journal Science Translational Medicine, looked at antibodies in serum samples from 48 health care professionals who had been exposed to experimental versions of the parent virus as well as the Alpha, Beta, Delta, and Omicron variants.”Our new findings show that two doses of mRNA vaccine do not provide protection against Omicron and that even a breakthrough infection on top of the vaccine does not help much. However, our previous research demonstrated that the booster can truly compensate for the shortcomings of the two doses “Shan-Lu Liu, a virology professor at Ohio State University in the United States, is the senior author of both studies.
